Winter Term 2020/2021

Signal Processing

For students of Biomedical Engineering

Lecture; Certificate Type A; ECTS: 3; English, Mandatory for Students of Biomedical Engineering.

The lecture will be uploaded as a video in Moodle.

Examination

The oral examination will last for 25-30 minutes and will cover the whole range of topics. No literature, script or utilities are permitted.

Admission to the exam will be granted after satisfactory completion of the assignment.

Lab Class

Exercise will be held by Philipp Koch, M.Sc.
Rating type B; Mandatory for Students of Biomedical Engineering

Rating Type B will be issued for a complete assignment, consisting of related exercises and a report on a given data set. Excercise results are to be handed in in print to the supervisor. On fullfilling the complete assignment, admission to the DSP I exam is granted.
